Modeling in Photonics

Realizing the Transparent Laser

When developing a fiber laser (or in fact any other kind of laser), one of the main challenges is that you cannot simply look into the device in order to see what exactly is going on inside.
That makes it difficult, of course, to find out how exactly to fix certain problems and optimize the performance.

Computer models can greatly support laser development and laser research by effectively letting you realize a fully transparent laser.

Wouldn't it be marvelous if you had a “transparent laser”, where you can easily see e.g. what are the optical intensities and excitation densities anywhere in the fiber, including their temporal evolution with arbitrary resolution?
It turns out that this is possible – with computer models of lasers (or e.g. ultrafast amplifier systems), as can be made with our software.
These are extremely helpful tools

for acquiring a detailed understanding of what goes on inside such devices,

and thus also for optimizing their designs.

Presentation on Efficient Laser Development With the Transparent Laser

In the following, we present a 25-minute video, where Dr. Paschotta explains

what special challenge you face in laser development,

how a computer model can be used to effectively obtain a transparent laser, and

how you can in practice work with a laser model, greatly reducing the cost and time required for the development.

Enjoy the video and take home important insights on how to make your laser development more efficient!
